'Doctor Who' Series 10 air date, spoilers: Matt Lucas of 'Alice in Wonderland' fame to return as Nardole?

Series 10 of "Doctor Who" will have 12 episodes, along with two Christmas specials.

In the upcoming series of the science-fiction programme, "Doctor Who," Matt Lucas, who is known for portraying the characters of Tweedle Dum and Tweedle Dee in "Alice in Wonderland," will be reprising his role of Nardole.

Rumours had earlier stated that Lucas was going to only appear in the Christmas special episode of "Doctor Who," BBC's long-running series. However, the 42-year-old actor has confirmed that he has been filming "more adventures for the series."

Besides Lucas, Peter Capaldi is also set to reprise his role of the Twelfth Doctor from the previous series. He will be joined by his faithful sidekick, Bill, a character portrayed by Pearl Mackie. The duo will continue on their adventures across space and time through the iconic time machine, TARDIS.

Series 10 of "Doctor Who" will have 12 episodes along with two Christmas specials (2016 and 2017). The show is scheduled to return to the small screen in April 2017 on BBC One. Show-runner Steven Moffat has assured fans that Capaldi will stay with the show for at least one more season.

This would be the first time Peter Mackie will serve as the Time Lord's new sidekick. She has been described as "irreverent" and "cheeky" in contrast to Capaldi's serious and focused Doctor. Unlike Clara, Doctor's previous sidekick, Bill, doesn't know much about the Doctor, and the strangeness between the two will surely make the upcoming series more interesting.

It has also been reported that the filming of the next series has been taking place at Kings Weston House in Bristol and a big party, most probably a wedding, will take place in one of the upcoming episodes. Reports have also stated that shooting has been done in Spain at the City of Arts and Science Museum in Valencia.
